Book excerpt: This book presents a comprehensive biological and ecological information about owls in the neotropic area. In addition the book covers topics such as threats and conservation strategies for these nocturnal birds of prey from 18 Neotropical countries. Owls are a good example of diversification processes and have developed evolutionary characteristics themselves. These species are found almost everywhere in the world but most of them are distributed in tropical areas and about a third of them live in the Neotropics. This biogeographic region has a high biodiversity and even share lineages of species from other continents because at some point all were part of Pangea. Although we still have much to know and understand about this diverse, scarcely studied and threatened group this work aims to be a precedent for future and further research on the subject.

This book was released on 2016-01-19 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: “Identificación Ecológica de Aves” trata sobre la identificación de aves silvestres desde la doble vertiente teórica y práctica. Estamos pues, ante un libro de Ornitología de campo, Birding o Birdwatching. Puede ser leído por cualquier persona amante de las aves y de la naturaleza en general. Aquellos lectores interesados en las aves de las montañas mediterráneas, lo encontrarán especialmente interesante. Para ponerle el nombre a un ave, ejercítese en el campo con unos prismáticos y una Guía de aves convencional, cuyo proceso de identificación esté basado en el plumaje. Un observador de aves, con seis meses o un año de práctica en la identificación por el plumaje, ya puede pensar en crecer técnicamente añadiendo al plumaje, las marcas y procesos desarrollados en este volumen bajo el concepto de identificación ecológica de aves, IEA. En la IEA, el número de marcas se amplía incluyendo además de las del plumaje, las de la estructura, el comportamiento y el uso del hábitat. Las diferentes aproximaciones o procesos IEA para identificar aves, se denominan de filtrado y de ID por impresión. Tales procesos son de naturaleza holística por obligación, pues no se basan en una sola marca, la del plumaje, si no en varias cuya suma provee una imagen fidedigna del ave integrada en su entorno. Buscamos una visión de conjunto. De esta manera, el plumaje deja de ser la única referencia para pasar a convertirse en el eslabón final, verificador, de la conclusión ID. El primer proceso holístico de “filtrado”, es un proceso lógico de eliminación progresiva de las aves candidatas de una Colección Básica. En primer lugar se determina la Familia incógnita para, a continuación, eliminar las especies de esa familia hasta que solo quede la especie incógnita. Esta aproximación es procesada en el hemisferio cerebral izquierdo. El segundo proceso holístico de “ID por impresión”, ha evolucionado a partir del filtrado. Mediante su aprendizaje y uso se generan, en el lóbulo derecho del cerebro, impresiones de conjunto del ave incógnita. La generación de impresiones, se produce tras un periodo de familiarización consciente de las especies de las familias incluidas en la Colección Básica, al asociar las imágenes de las aves silvestres en observación con las palabras de la descripción de sus marcas. También ayuda a la generación de impresiones, la comparación en gabinete de las marcas entre las especies de una misma familia. Cuando el observador combina el uso de las dos aproximaciones holísticas, de filtrado e impresión, está usando la Identificación Ecológica de Aves. En ella, se implican ambos lóbulos del cerebro, lo que multiplica la eficacia de sus conclusiones ID. El observador adquiere, con este punto de vista ecológico, una comprensión más amplia de las aves. Por último, para identificar aves raras o muy semejantes entre si, se aplica la ID avanzada del plumaje, que no es objeto de este volumen 1. En la ID avanzada por el plumaje, se elaboran agregados de marcas del color y del plumaje. En el volumen 1, los procesos teóricos de identificación, son llevados a la práctica de campo, proporcionando al observador procedimientos de aprendizaje y de aplicación sistemáticos. Las descripciones técnicas se acompañan de herramientas gráficas como diagramas y fotocomposiciones. Se proponen ejercicios de campo para adquirir experiencia. Numerosos ejemplos de campo ayudan a visualizar los procesos prácticos.

This book was released on 1998 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: Delegations from 54 members of the Organization and observers from 8 intergovernmental and international non-governmental organizations met at FAO Headquarters to prepare for the Consultation on the Management of Fishing Capacity, Shark Fisheries and Incidental Catch of Seabirds in Longline Fisheries. The meeting discussed draft plans of action for the conservation and management of sharks and for the reduction of the incidental catch of seabirds in longline fisheries, as well as elements for a draft plan of action for the management of fishing capacity. This report summarizes the debates that took place. It also contains the guidance provided by the meeting to the FAO Secretariat about how best to proceed with the development of the documents that will be presented to the consultation proper. This guidance includes inter alia recommendations to the effect that the plans of action must assign the responsibility for actions amongst states (including other fishing entities), regional fishery bodies and international organizations. The plans should include provision for implementation and monitoring, including the issue of how to promote compliance by non-members of regional fishery organizations as well as by flag-of-convenience vessels. It was requested that technical assistance needs of developing countries be specified. It was suggested that the cost for any activities to be carried out by FAO, as part of the implementation of any international plan of action, should not be covered by extra-budgetary sources alone.--Publisher's description.

Book excerpt: Results of a reconnaissance are presented for part of the south-central Peruvian coast. These data constitute the initial phase of a project involving a general survey of marine desert ecology. Broad objectives include reconstruction of the late-Pleistocene paleogeographic environment and assembly of land-based evidence for previous Peru Current deflections. Contemporary problems of human ecology are considered after systematic review of existing literature on geology, geomorphology, oceanography, meteorology, botany, and archaeology. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: This authoritative title is the definitive avifauna covering the Iberian Peninsula. The Iberian Peninsula is one of Europe's most ornithologically varied regions offering a host of regional specialities. It includes famous birding hotspots such as the Coto Donaña wetlands, mountainous areas such as the Picos de Europa and the Pyrenees, the Mediterranean cork and holm oak forests of the southwest, the migration crossroads of the Strait of Gibraltar and the steppe-like plains of Extremadura and Alentejo. Large numbers of birders from around Europe visit the region to see this wealth of winged wildlife, but to date there has been no comprehensive regional avifauna in English. Birds of the Iberian Peninsula is a national avifauna that fills this gap in the ornithological literature. Full-colour throughout, the book begins with authoritative introductory chapters covering subjects such as geography, climate, habitats, the history of Iberian ornithology and the composition of the avifauna. The species accounts then cover every species recorded in mainland Spain, the Balearic Islands, Portugal, Gibraltar and Andorra, including the many vagrants. For each species there is detailed treatment of distribution – with maps of breeding and wintering ranges – habitat selection, population trends, historical and current status, migration and conservation.

This book was released on 2009-12-09 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: As in the terrestrial environment, most data collection from freshwater habitats to date falls into the survey, surveillance or research categories. The critical difference between these exercises and a monitoring project is that a monitoring project will clearly identify when we need to make a management response. A Model for Conservation Management and Monitoring Monitoring (as defined by Hellawell) is essentially a tool of practical conservation management, and Fig. 1.1 shows a simple, but effective, model for nature conser- tion management and monitoring. The need for clear decision-making is implicit in this model. First we must decide what would represent a favourable state for the key habitat or species, and then we must decide when to intervene if the state is (or becomes) unfavourable. A third, often overlooked, but equally important, decision concerns when we would consider the habitat or species to have recovered; this is unlikely to be the same point that we became concerned about it. This decision not only has resource imp- cations, it can also have major implications for other habitats and species (prey species are an obvious example). All of these decisions are essential to the devel- ment of an efficient and effective monitoring project.
